This was breaking sqlite with the machine verifier because operand 0 was a def according to tablegen, but didn't have the 'isDef' flag set. Looking at the ISA, its clear that this operand is a source as writing to st(0) is implicit. So move the operand to the correct place in the td file. rdar://problem/20751584 llvm-svn: 236183
